What Controls a RC Car?

Remote Control Cars, or RC cars, are a fun and popular way of racing, collecting and even engineering. They have become an incredibly popular hobby for both adults and children. From the spectrum of RC car types Рfrom nitro to electric to gas-powered Рto the range of available parts, there’s no shortage of options when it comes to RC car customization.

The main components that control a RC car are the Remote Control Unit (RCU), Battery and Motor. The Remote Control Unit is a device consisting of several buttons and a joystick that is used to control the car.

The battery provides power to the motor so it can move. The motor is then connected to the wheels of the car via gears which spins them and makes the car move.

The Remote Control Unit sends signals via radio frequencies which are picked up by an antenna on board the car. The signal is then sent to an on-board microcontroller which interprets it into instructions telling it what direction and how fast it should go. This instruction is then sent to a motor driver circuit which controls how much power is being supplied to each motor so that they work together in order for the car to move in the direction desired.

Additionally, additional components like steering servos can be installed in order for more precise steering control. These servos take instructions from the microcontroller and adjust the angle of each wheel accordingly.


In conclusion, what controls a RC Car is its Remote Control Unit (RCU), Battery, Motor, Microcontroller, Motor Driver Circuit and optional Steering Servo. All these components work together in order for you to be able to drive your RC Car around with ease.
